Function Documentation

ldiv()

ldiv_t ldiv	(	long	x,
		long	y
	)

Computes both the quotient and the remainder of the division of the numerator x by the denominator y.

Computes both the quotient and the remainder of the division of the numerator x by the denominator y. Computes quotient and remainder simultaneously. The quotient is the algebraic quotient with any fractional part discarded (truncated towards zero). The remainder is such that quot * y + rem == x.

Computes the quotient (the result of the expression x/y) and remainder (the result of the expression xy) simultaneously.

Parameters

x	integer values
y	integer values

Returns

If both the remainder and the quotient can be represented as objects of the corresponding type (int, long, long long, imaxdiv_t, respectively), returns both as an object of type

If either the remainder or the quotient cannot be represented, the behavior is undefined.
